3. The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25 V. In case of exceeding this specification, the IC must be

operated on condition that the Input Voltage is up to 5.5V and the total operating time is within 500 hrs.

4. VIN > 1.4 V condition is dominant against this specification

5. The value of quiescent current is excluding the pull−down current of CE and AE pin
